The Goodman 20201902 23-inch Condensate Drain Hose Tube is a genuine OEM part for Goodman GKS90704CXAE high-efficiency gas furnaces. Cut to a factory length of 23 inches, this flexible tube routes acidic condensate between the collector box, drain trap, and outlet. Aged hoses stiffen, crack, or clog and are a leading cause of condensate leaks, pressure-switch faults, and no-heat lockouts. A fresh hose restores clean, gravity-fed drainage.

Specifications

OEM Part Number: 20201902
Part Type: Condensate Drain Hose / Tube
Length: 23 inches
Brand: Goodman (OEM)
Equipment: High-Efficiency Gas Furnace
Primary Fit: GKS90704CXAE

OEM vs. Generic

This genuine Goodman OEM hose arrives at the exact 23-inch length and correct bore, so it presses cleanly onto the factory barbs and follows the drainage slope Goodman designed. Cutting generic tubing to length risks the wrong diameter, kinks, or a hose too short to reach — any of which can block flow. OEM removes the guesswork.

Installation Difficulty

Easy (1–2 of 5). Pull the old hose off the fittings and press the new one on; add clamps if originally used. Shut off power first and verify a continuous downward slope with no kinks. Test drainage on startup.

Ships fast, fit guaranteed.
